WINDOW-SCREEN.

ZPECIFIGATION forming part of Letters Patent No. 279,882. dated June 19, 1883.

Application filed A ix-i113. 1883. No model.) 7

To all whom it may concern MER, a citizen of the United States, residing at Patchogue, in the county of Suffolk, Long Island, State of New York, have invented new and useful Improvements in XVindow-Screens, of which the following is a specification.

The invention relates to screens which are attached to windows for preventing the. inroads of flies, mosquitoes, Ste.

The objects of my improvements are, first, to produce a window-screen that shall'be a perfect protection against flies and insects without regard to the elevation of the sash second, to simplify the construction of such devices, so that they may be fitted to windows by unskilled labor; and, third, to cheapen their cost. I attain these objects by the manufacture and construction hereinafter described, and illustrated in the accompanying drawings, in which Figure 1 represents a view in perspective of the inner side of a window-frame as having both upper and lower sash protected by my improvements; Fig. 2, a similar view, showing both upper and lower sash partially open, the fabric netting of the screens being cut away, exposing the sash and the horizontal guard-strips for additional protection when the sash or either of them are open; Fig. 3, a

perspective of the screen for the upper sash;

Fig. 4:, a similar View of the lower screen, the upper rod of which is provided with a horizontal guard-strip adapted to fit so nearly against the window pane or panes as to pre- 'vent the ingress of any flies which may have passed upward between the netting and bottom rail of said sash when raised. Fig. 5 is a perspective of one of the lipped brackets a, used in securing the top rod of the upper screen 5 Fig. 6, a perspective of one of the brackets a, which are fastened in pairs upon the beads-to form holdingsockets for the screen stretcherrods and Fig. 7, a vertical longitudinal sec tion of the window frame with the screens applied, both sashes being partially open. In this view the relations of the guard-strips to the screens are plainly shown.

On the top bar or meeting-rail of the lower sash a rubber guard-strip (similar to that described in Fig. 4) is fixed, extending horizon- V tally toward the window-panes of the upper sash, so as to stop flies and mosquitoes, which might otherwise pass through the aperture between the sash when either sash is partially open. l

In the manufacture of the screens for both sashes I fasten flexible netting of fabric or suitable material to top and bottom stretcherrods, and apply them to the windows upon the inside, as will be presently described.

Referring to the drawings, A is the windowframe; B, the lower and C the upper screen. Brackets a a. a a a are used in securing the stretcher bars or rods (Z d to the beads c c of the window-frame. Upon the top of the upper stretcher-rod d of the lower screen, 13, I tack a guard strip, f, of india-rubber, felt, fabric, or folded netting, in such manner that it shall project horizontally outward and be fitted so closely to the pane or panes of glass 8 and sash-bars as to prevent the ingress of flies and mosquitoes, which otherwise might pass between the netting screen and bottom rail of the sash and over the stretcher-rod. \Vith this lower screen the brackets care used upon both heads 6 c of the frame, as shownone at the bottom on each side to form, in connection with the window sill or nosing 9, seat sockets for the lower stretcher-rod d, and three on each side near the meeting of the sash to form two sockets on each side, one for the upper stretcher-rod of the lower screen and one for the lower stretcher-rod of the upper screen,

-O, as plainly seen in Figs. 1 and 2. The sockets for the top stretcher-rod of the upper screen, 0, are formed by the brackets a and the crossbead z of the window-frame. The bracket a. is illustrated in Fig. 5, and is cast or struck up with a lip, of, projecting beyond its edge to form a holding or stop seat for the said top stretcher-rod. This construction is necessary, because there would otherwise be nothing for the upper stretcher-rod to rest against, the upper sash of a window running, as it does, in a separate guideway from the lower one.

To protect the opening made between the sash by the raising of the lower sash or the lowering of the upper one, I fasten a, guardstrip, f, similar to guard-strip f, above de scribed, upon the top rail of the lower sash. Inasmuch as I have preferred this cheap and simple construction of screen wherein 1 the stretcher-rods are held in sockets formed by the brackets a a a, (especially near the meetingrails,) there would be a space,k, Figs. 1 and 7, between the stretcher-rods of the screens, forming a way of ingress for flies if either sash were raised or lowered, and whether the top sash be stationary or not. Thus the guardstrips, in combination with the screens, form a perfect protection. The side edges of the screens are protected from wear and kept straight to the sides of the window-frame by being re-enforced with any suitable border binding, m, or they may be lapped and hemmed.

In applying the netting or other fabric to the stretcher-rods for the lower sash, suffioient tension is required to produce a smooth, even surface, which, when the screen is placed in position in contact with the sash, is always in such close juxtaposition with the bottom rail thereof as to form a protection against flies, whatever the elevation of the sash may be.

The screens are readily removable and replaceable, and their tension serves as an aid to holding them in their sockets.

I design to furnish the screens ready mounted for sale with the brackets, and strips, and stretcher-rods, and to furnish the stretcherrods and accompanying parts for sale, so that the purchaser may make any size "of screen and attach any desired netting.

I claim- 1. The lower screen of awindow-screen, consisting of fabric netting or its equivalent, stretched on top and bottom rods, and having its top rod provided'with a horizontal guardstrip, f, substantially as and for the purpose described.

2. The combination of the lower screen, B, provided with the guard-stripf, and the lower sash of the window provided with a guardstrip, f, substantially as and for the purpose set forth.

3. The combination, with the upper screen, 0, composed of fabric netting and top and bottom stretcher-bars, of the brackets a a, having the lips a whereby sockets are formedfor the nppercstretcher-bar and stops to its inward movement, as set forth.

In testimony whereof Ihave hereunto set my hand in the presence of two subscribing witnesses. 7
